No. 232,555 Ciaims priority, application Great Britain Get. 23,1961 6 Claims. (Cl. 229-68) The present invention relates to an envelopetype packet suitable inter alia for the reception of gramophone records.Such packages are frequently referred to as record sleeves and willhereinafter be referred to as sleeves which expression shall not in thisspecification be limited specifically to gramophone record sleeves.

In our co-pending application No. 1914, now Patent No. 3,061,171, thereis described and claimed a sleeve formed from two separate pieces ofsheet material joined around three edges so that the front of the sleevecan be made of a different material from, and have a different finish tothe back. In the construction shown and claimed in this co-pendingapplication the front and back pieces of material were joined around theedges on three sides by the ilap or aps extending from one of thecovering sheets applied to one of the sides of the sleeve. Such aconstruction gives a suitably strong edge if the iiap is made ofsutiiciently stout material and in the case of gramophone record sleevesthis has usually comprised good quality paper laminated with plasticfilm such as a transparent cellulose acetate lm.

An object of the present invention is to provide a construction ofsleeve in which the joins between two adjacent edges of sheet materialis made and reinforced without the requirement of having a strongoverlapping material covering the edges of the sheet material and themarginal portions adjacent thereto.

According tov the present invention a sleeve for receiving a gramophonerecord and similar dat articles has a sleeve edge formed by a marginalextension of one of the faces of the sleeve folded back upon itself toform the edge of the sleeve, the other face of the sleeve being cutshort so that its edge lies close to and in the same plane as the foldedmarginal extension, there being provided between the two edges a closingsheet-like element which is adhered to the inner face of one of theedges and the outer face of the other edge. Conveniently the closingelement is a strip or sheet of paper plastic or like material.

Normally the material passing between the join comprises an all oversheet which serves also to carry printed matter on that side of thesleeve. Conveniently, the edge and the marginal portions may be coveredby material which may comprise the flap of a sheet secured to the otherside of the sleeve and in the case of record sleeves may constitute thefront of the sleeve and carry pictorial and/ or writing matter.

The invention will now be described with reference to the accompanyingdrawings in which:

FIGURE 1 shows diagrammatically and in cross-section a fragmentaryportion of one edge of a sleeve suitable for gramophone records; and

FIGURE 2 shows in section one stage in the assembly of the sleeve.

Referring to FIGURE 1 which shows a cross-section of one edge of arecord sleeve the body of the sleeve comprises a front sheet 1 and aback sheet of chipboard. Sheets 1 and 2 may be two separate sheets orthey may comprise one sheet of chip-board folded to form one edge. Theedges of the sleeve not formed by a fold between the sheets 1 and 2 areformed by extending the edge of the sheet 1 beyond the required ultimatedimensions of the sleeve so as to form a marginal portion 3 and sheet 2is cut short of the required dimensions of the sleeve 3,1%,870 PatentedJan. 7, 1964 ICC by an amount equal to or slightly greater than theWidth of the marginal portion 3. To assist folding the sheet 1 may becut partially or scored as at 4. The sheet 2 is assembled with the sheet1 as shown in FIGURE 2 and a thinner sheet for example of paper 5 of thesize of the ultimate sleeve is applied to the sheet 2 and may be gluedthereto, so that the marginal portion of the sheet 5 extends up to ornearly up to the point of fold.

The face 6 of the marginal portion 3 after having an adhesive appliedthereto is then turned over to form the fold to the position shown inFIGURE l so that it adheres to the face of the paper sheet 5. In thisway the marginal portion 3 is held in position and any adhesive surplusto requirements is prevented from leaking into the fold and causingsticking of the inside faces of the front and back of the sleeve. Thenormal flap 8, forming an extension of the facing sheet 7 is folded overthe edge and secured down to the back of the sleeve to cover the joinbetween the portion 3 and the edge of the sheet 2 and also to reinforcethe edge. In view of the fact the edge of the sleeve, which is where thesleeve is most likely to distort, is reinforced by forming it from thefolded Inarginal portion of sheet 1 the ap 8 does not require to be ofany specific or special strength. However, if reinforcement is requiredalong the edge then the liap 8 can be adhered around the edge by meansof a polyvinyl or like adhesive which when set provides a plasticreinforce- Each edge of the sleeve may, if desired, be constructed inthis manner and whilst it is normal for the front sheet to be extendedmarginally to form the fold it will be realised that on one or more ofthe edges of the rear sheet may be extended and the front sheet cutshort. The sheet 5 may, if desired, consist merely of a strip of paperor other suitable material which is adhered marginally to the sheetwhich is cut short so as to extend between the edges of the front sheetand the back sheet of chip-board in the manner described with referenceto FIGURES 1 and 2.

In addition to the great advantage afforded by the present invention sofar as the reinforcing of the edges is concerned it has been found thatby being able to fix down the marginal portion 3 this can be reduced toa minimum width. When the sleeve is used as a record sleeve this has theadvantage that the join between the marginal portion 3 and the sheet 2does not lie upon the playing portion of the record which, if it did,might damage the delicate playing grooves of the record. Furthermore,the sheet 5 extending into the inside of the sleeve at the marginal edgeportion acts as a flashing and prevents any adhesive squeezed out frombetween it and the inside face of the marginal portion 3 leaking intothe inside of the sleeve to stick the inside faces of the sleevetogether.

By means of the present invention the strength of the edge does not relylargely upon the strength of the Hap S as it has done heretofore inknown constructions where the overlapping iap 8 constitutes the solejoin between the front and back sheets. In such prior constructions ithas been proposed to reinforce such a join by gluing a further strip ofmaterial over the edge portion. This, however, is expensive in that itoccupies a separate operation in the manufacture of such sleeves.

Furthermore, since the operations necessary to form a sleeve `do notinvolve overlapping material to form the join the invention may be usedin the construction of sleeves in which the llap 8 is eliminated. Insuch cases the join 'between the marginal portion 3 and the sheet 2 mayif desired be covered by a narrow strip of material, for example, astrip of glued paper. This enables the front `sheet to be eliminated andthe chip-board 1 can where desired, carry pictorial or other matter.Alternatively, the edge may be covered by a strip of material.

Whilst the invention has been described specifically with reference to asleeve in which the body comprises a front or back of chip-board it willbe realised that the invention can be `applied to any other form ofsleeve constructed from sheet material.
